Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to a display screen cabinet mounting and fixing structure and a display screen. Background Technology

[0002] With the rapid development of modern technology, large LED displays have been widely used in advertising, information display, stage performances, and many other fields. Large LED displays are typically composed of numerous individual display cabinets assembled together. The rationality and stability of their installation and fixing structure play a crucial role in the normal operation and safety of the display.

[0003] In traditional display cabinet installation methods, corner clips typically employ a combination of U-shaped and straight corner clips, secured to the mounting rods using bolts at the four corners. However, in practical applications, especially for tall display screens, this installation method reveals a series of significant problems.

[0004] First, traditional installation methods involve numerous components, each requiring manual assembly and securing. During assembly, some bolts, though inserted into their corresponding holes, are often not fully tightened. In this situation, workers operating at heights in confined spaces face significant challenges; even slight swaying or accidental contact can easily cause these loosened components to fall off. Furthermore, bolts require washers before insertion; however, workers at heights are prone to hand tremors, causing washers to easily detach. This risk of components falling from heights poses a serious threat to the safety of personnel and equipment below. A fall could cause irreparable damage, disrupt installation, increase costs, and create significant safety hazards.

[0005] Secondly, the combination of numerous components greatly increases the difficulty of working at heights. Workers at height must precisely position and install each component, as well as perform delicate operations such as tightening bolts. This makes manual operation extremely inconvenient, the installation process cumbersome and lengthy, requiring significant manpower and time costs, and resulting in low installation efficiency.

[0006] Based on this, the present invention provides a novel display screen cabinet mounting and fixing structure and display screen to overcome the above-mentioned defects. Utility Model Content

[0013] Furthermore, a first pad is fixedly provided at the position where the first axial limiting member is installed between the corner fastener and the clamping fastener, and the first axial limiting member is disposed on the first pad.

[0014] Furthermore, the first mounting hole and the second mounting hole are the same size, and the first mounting hole is smaller than the outer diameter of the first screw head section of the first connecting screw.

Detailed Implementation

[0037] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The present invention will be described in detail with reference to specific embodiments:

[0039] like Figures 1 to 8 As shown, this utility model provides a display screen enclosure mounting and fixing structure, which is used to lock and fix the display screen enclosure onto the fixing rod 1, thereby achieving fixed installation of the display screen enclosure. The display screen enclosure mounting and fixing structure includes a clamping assembly and an axial constraint unit.

[0040] The clamping assembly includes a corner clip 2 located on the front side of the fixing rod 1, a clamping fastener 3 located on the rear side of the fixing rod 1, and a first connecting screw 4. The clamping fastener 3 has two first mounting holes 30, and the corner clip 2 has a second mounting hole 20 opposite to the first mounting holes 30. The first connecting screw 4 passes through the first mounting holes 30 and the second mounting holes 20 in sequence and is threadedly connected to the display screen housing, thereby achieving fixed installation of the display screen housing on the clamping assembly.

[0041] The axial constraint unit includes two first axial limiting members 5 disposed on the corner fastener 2 and / or the clamping fastener 3, which cooperate with the first connecting screw 4 to limit the axial displacement of the first connecting screw 4 and prevent the first connecting screw 4 from falling out of the mounting hole. At least one first axial limiting member 5 is disposed on the corner fastener 2 to prevent separation of the corner fastener 2 from the clamping fastener 3.

[0042] Specifically, when both first axial limiting members 5 are mounted on the corner fasteners 2, firstly, pull out the two first connecting screws 4 and snap them into the corresponding first axial limiting members 5. Then, pull the clamping fastener 3 outwards to increase the installation space between the clamping fastener 3 and the corner fastener 2, allowing the fixing rod 1 to be placed within this space. Finally, tighten the two first connecting screws 4. The tension generated by the threaded connection causes the corner fastener 2 and the clamping fastener 3 to tightly clamp the fixing rod 1, thus locking and fixing the display cabinet mounting structure onto the fixing rod 1.

[0043] When one first axial limiting member 5 is located at the corner fastener 2 and the other is located on the clamping and fixing member 3, the first connecting screw 4 is first pulled out and snapped into the corresponding first axial limiting member 5, as follows: Figure 8 As shown. Then, using the first connecting screw 4 at the location of the first axial limiting member 5 at the clamping and fixing member 3 as the rotation hinge point, rotate the clamping and fixing member 90 degrees. At this time, the display screen cabinet mounting and fixing structure can be placed in the corresponding position of the fixing rod 1. Finally, tighten the two first connecting screws 4 to make the corner fastener 2 and the clamping and fixing member 3 fit tightly together, completing the locking and fixing on the fixing rod 1.

[0044] The display screen cabinet mounting and fixing structure designed in this utility model consists of a clamping assembly and an axial constraint unit. By setting two first axial limiting members 5 adapted to the first connecting screw 4 on the corner fastener 2 and / or the clamping fixing member 3, the axial displacement of the first connecting screw 4 can be effectively limited, preventing it from falling out of the mounting hole. Furthermore, at least one first axial limiting member 5 is provided on the corner fastener 2, preventing the corner fastener 2 from separating from the clamping fixing member 3, thus forming a single integrated component for the display screen cabinet mounting and fixing structure. When this integrated component is installed on the fixing rod 1, the risk of components falling from height during installation is significantly reduced, effectively ensuring the safety of high-altitude operations. In addition, the structure has a simple design, is easy to install and operate, and greatly improves installation efficiency.

[0045] Furthermore, in some specific embodiments, design schemes for preventing the first connecting screw 4 from falling out of the mounting hole are provided, such as... Figure 5 As shown, the specific technical solution is as follows:

[0046] The first connecting screw 4 is divided into a first screw head section 40, a first optical axis section 41, and a first threaded connection section 42 arranged sequentially along the axial direction. The outer diameters of both the first threaded connection section 42 and the first screw head section 40 are larger than the outer diameter of the first optical axis section 41. The first screw head section 40 can be designed with reference to the bolt head structure. In this embodiment, the first mounting hole 30 and the second mounting hole 20 are of equal size and smaller than the outer diameter of the first screw head section 40 of the first connecting screw 4. Correspondingly, the connecting screw will not detach from the direction from the screw head section to the threaded connection section.

[0047] The axial direction of the first axial limiting member 5 is perpendicular to the axial direction of the first connecting screw 4, and the end of the first axial limiting member 5 is close to the outer wall of the first optical axis section 41 of the first connecting screw 4 and forms a limiting fit with the first threaded connection section 42, thereby preventing the first connecting screw 4 from falling off along the direction from the threaded connection section to the screw head section, thereby realizing the bidirectional axial limiting of the first connecting screw 4.

[0048] In a more specific embodiment, a first pad 6 is fixedly provided at the position where the first axial limiting member 5 is installed between the corner fastener 2 and the clamping fastener 3, and the first axial limiting member 5 is disposed on the first pad 6. The provision of the first pad 6 can increase the bonding strength between the connecting screw and the corner fastener 2 and the clamping fastener 3, and at the same time, provide placement space for the first axial limiting member 5.

[0049] In this embodiment, the first axial limiting member 5 can be a bolt, screw, etc., which can be designed and selected by those skilled in the art based on the actual situation.

[0050] Furthermore, in some specific embodiments, the corner clip 2 is provided with a planar contact portion 21 on the front side of the contact with the fixing rod 1, which increases the contact area and thereby enhances the connection strength between the display screen cabinet mounting and fixing structure and the fixing rod 1 when locked.

[0051] Furthermore, in some specific embodiments, the left and / or right sides of the corner fastener 2 are provided with supporting protrusions 22 extending towards the clamping fastener 3. These supporting protrusions 22 support the first connecting screw 4, enhancing connection stability. Simultaneously, the surface of the supporting protrusion 22 away from the corner fastener 2 can form a surface contact with the clamping fastener 3, increasing the contact area and further enhancing connection stability. Additionally, when one first axial limiting member 5 is located at the corner fastener 2 and the other at the clamping fastener 3, the supporting protrusion 22 can also serve as a support point for the rotation of the clamping fastener 3.

[0052] Furthermore, in some specific embodiments, the clamping fastener 3 is a U-shaped plate structure, the non-open end face of the U-shaped plate structure is a plane, and it abuts against the outer wall of the fixing rod 1 to increase the contact area and thus enhance the connection stability.

[0053] Correspondingly, the first pad 6 can be fixedly set in the groove at the opening end of the U-shaped plate structure, or the first pad 6 can also be set in the groove at the opening end of the U-shaped plate structure where the first axial limiting member 5 is not set, to enhance the connection strength.

[0054] Furthermore, in some specific embodiments, the corner fastener 2 is also provided with a second connecting screw 7, and correspondingly, the corner fastener 2 is provided with a third mounting hole 23, through which the second connecting screw 7 passes and is threadedly connected to the display screen housing.

[0055] Furthermore, the corner clip 2 is also provided with a second axial limiting member 8 that cooperates with the second connecting screw 7 to limit the axial displacement of the second connecting screw 7 and prevent the second connecting screw 7 from falling out of the mounting hole.

[0056] Specifically, the second connecting screw 7 can be designed with reference to the first connecting screw 4. The second connecting screw 7 is divided into a second screw head section 70, a second optical shaft section 71, and a second threaded connection section 72 arranged sequentially along the axial direction, as shown below. Figure 7 As shown. The outer diameters of both the second threaded connection section 72 and the second screw head section 70 are larger than the outer diameter of the second optical axis section 72. The second screw head section 70 can be designed with reference to the bolt head structure. In this embodiment, the third mounting hole 23 is smaller than the outer diameter of the second screw head section 70 of the second connecting screw 7, and correspondingly, the connecting screw will not detach from the direction along the screw head section to the threaded connection section.

[0057] The axial direction of the second axial limiting member 8 is perpendicular to the axial direction of the second connecting screw 7, and the end of the second axial limiting member 8 is close to the outer wall of the first optical axis section 41 of the second connecting screw 7 and forms a limiting fit with the second threaded connection section 72, thereby preventing the second connecting screw 7 from falling off along the direction from the threaded connection section to the screw head section, thereby realizing the dual-axis limiting of the second connecting screw 7.

[0058] More preferably, two of each of the first connecting screw 4 and the second connecting screw 7 are provided, and they are arranged in a 2-way configuration. 2. Array-style layout.

[0059] Furthermore, in some specific embodiments, the corner clip 2 is provided with a second pad 9 on the side near the fixing rod 1. The second pad 9 has a fourth mounting hole 90 opposite to the third mounting hole 23. The second connecting screw 7 passes through the fourth mounting hole 90 and the third mounting hole 23 in sequence and is threadedly connected to the display screen housing. The second axial limiting member 8 is provided on the second pad 9. The provision of the second pad 9 can increase the connection strength between the connecting screw and the corner clip 2, and at the same time, provide placement space for the second axial limiting member 8.

[0060] It should be noted that the connecting screw is fitted with ordinary washers and elastic washers, and then inserted into the corresponding mounting holes. These are all conventional technical means and will not be described in detail in this utility model.

[0061] Based on the aforementioned display screen cabinet mounting and fixing structure, this utility model also provides a display screen, which includes a plurality of display screen cabinets and a display screen cabinet mounting and fixing structure, wherein the display screen cabinet mounting and fixing structure is the aforementioned display screen cabinet mounting and fixing structure.
